That derating curve matters for a panel that runs warm: the breaker does not force a larger frame just because ambient hits 50 °C. The 121 kA breaking capacity at 415 V (187 kA at 240 V, 75.6 kA at 440 V, 30 kA at 500 V, 17 kA at 690 V) means it can interrupt a fault of that magnitude without upstream coordination failure — sized for high-fault industrial distribution. The TM240 thermal-magnetic release provides inverse-time overload and instantaneous short-circuit protection, and the integrated shunt trip (STL) allows remote tripping for emergency-stop or supervisory control. ## Line protection design and shunt trip The shunt trip release (STL) operates on a separate control voltage, allowing the breaker to be opened by a remote pushbutton, PLC output, or safety relay. ## Mounting dimensions and panel integration The 3VA1220-5EF32-0KA0 measures 105 mm wide, 158 mm high, and 70 mm deep — a standard 3-pole MCCB footprint for SENTRON 3VA frames.","metaTitle":"Siemens 3VA1220-5EF32-0KA0 SENTRON MCCB, 200 A, 3-Pole, 121","metaDescription":"Siemens SENTRON 3VA1220-5EF32-0KA0 molded case circuit breaker, 200 A rated, 3-pole, 121 kA breaking at 415 V.

The 3VA1220-5EF32-0KA0 carries a higher 200 A rating and higher breaking capacity (121 kA at 415 V) than the 3VA1110-5ED36-0AC0 — if the original panel's busbars and cable are sized for the lower rating, the breaker will mount but the upstream protection and conductor sizing must be verified for the higher current."},{"question":"What compliance documentation does Siemens provide for 3VA1220-5EF32-0KA0?","answer":"The SENTRON 3VA series carries IEC 60947-2 certification for molded case circuit breakers.
